体外循环心内直视手术对机体免疫防御功能的影响

本文报告30例体外循环(CPB)心内直视手术患者血清免疫球蛋白(IgG、IgA、IgM)和补体C_3含量、中性白细胞的吞噬能力和PHA淋巴细胞转化反应的变化。结果提示,血清IgG含量和PHA淋巴细胞转化反应于CPB结束时明显降低并持续一周以上(P<0.05或0.01),术后两周恢复至术前水平,血清IgA和IgM仅在CPB结束时降低(P<0.01),中性白细胞吞噬能力和补体C_3则在CPB结束时和术后一天明显降低(P<0.05或0.01)。因此得出结论:CPB心内直视手术对机体的免疫成分和防御功能有不同程度的抑制作用,尤其是对IgG和PHA淋巴细胞反应影响更大。

Abstract：

Objective To explore the long-term effect of endemic arsenism on oxidative stress and immune function, and to provide scientific basis for prevention and treatment of the disease in the areas. Methods In 2009, Using cluster sampling and typical investigation, the cross-sectional study was completed. The patient groups and the internal control group were selected in the arsenism areas after 5 years quality improvement of drinking water(Silizhuang village, Daying village and Gucheng village in Shanyin county, Gucheng city, Shanxi province) and they were divided into mild, moderate, severe case and internal control groups, respectively. The external control group was selected in a non-arsenism area(Yangzhuang village in Heshengbu city). The Oxidative stress indicators were determined and analyzed [serum superoxide dismutase (SOD) activity was determined with xanthine oxidase method, glutathione peroxidase(GSH-Px) activity was determined with 2-thio-2-nitrobenzoic acid method, and mmuuity malondisldohyde(MDA) levels was determined with thiobarbituric acid method]. The immune function was determined and analyzed [immunoglobulin G (IgG) was determined with radioimmunoassay method, and serum lysozyme was determined with turbidimetric method]. Results A total of 252 people were surveyed, in which the external control group, the internal control group, mild, moderate and severe patient groups were 56, 57, 49,44 and 46, respectively. Serum SOD activities were (72.19 ± 11.75), (66.96 ± 12.02), (49.79±11.07), (48.54 ±10.56) and (47.68 ± 10.68)kU/L, respectively. The difference of serum SOD activities between the groups was statistically significant(F = 52.42, P ＜ 0.01 ). Serum SOD activities in the external control group were significantly higher than other groups (all P ＜ 0.05). The value in the internal control group was significantly higher than the 3patient groups (all P ＜ 0.05). There were no significant differences between the case groups (P ＞ 0.05). Serum GSH-Px activities of the five groups were (197.41 ± 38.54), (195.02 ± 31.93), (187.26 ± 28.22), (187.24 ± 25.40),(186.88 ± 21.84)U/mg, respectively, and the difference between the groups was not significant(H = 4.21, P ＞0.05). Serum MDA levels of the five groups were (4.51 ± 2.14), (5.88 ± 2.00), (6.44 ± 2.83), (5.89 ± 2.57),(5.88 ± 2.40)μ mol/L, respectively, and the difference between the groups was statistically significant(F = 3.36,P ＜ 0.05). The external control group was significantly lower than other groups(all P ＜ 0.05). No significant difference was observed between other groups(all P ＞ 0.05). Serum IgG levels were(11.16 ± 2.08), (8.15 ± 1.44), (8.77 ±2.54), (9.19 ± 1.97), (8.44 ± 2.52)g/L, respectively, and the difference between the groups was statistically significant(H = 52.92, P ＜ 0.01 ). The external control group was significantly higher than other groups(all P ＜0.05). No significant difference was observed between other groups(all P ＞ 0.05). Serum lysozyme levels were (13.57 ± 5.16), (10.05 ± 3.96), (8.78 ± 3.35), (8.72 ± 3.76), (9.38 ± 4.26)mg/L, respectively, and the difference between the groups was statistically significant (H = 35.00, P ＜ 0.01 ). The external control group was significantly higher than other groups(all P ＜ 0.05). No significant difference was observed between other groups(all P ＞ 0.05). Conclusions The effect of arsenic on the body's oxidative stress response and immune function persists after 5 years of drinking low arsenic water. In addition to intensify arsenic removal from drinking water, it should also strengthen the monitoring of population's health in the diseased areas.     

Effect of different anesthesia methods on erythrocyte immune function in mice

ObjectiveTo explore effect of different anesthesia methods and different anesthetics on erythrocyte immune function in mice.MethodsThe mice were anesthetized by isoflurane and ether inhalation, and also under intraperitoneal anesthesia with sodium pentobarbital and chloral hydrate. Blood was collected from the ventro-cardinal vein. Automatic blood cell analyzer was used for routine blood examination, and the canthine oxidase method was used to measure the superoxide dismutase (SOD) activity. Lipid peroxidation product malondialdehyde (MDA) was measured with TBA, and glutathione peroxidase (GSH-Px) was measured with DTNB, and then the effect of different anesthesia methods and different anesthetics on erythrocyte immune function in mice was observed.ResultsHct level of chloral hydrate intraperitoneal injection group was significantly higher than the other three groups (P<0.05). And the MDA levels in the pentobarbital sodium group were significantly higher than the other three groups (P<0.05). SOD and GSH-Px of the chloral hydrate and sodium pentobarbital intraperitoneal injection group were significantly lower than the other two groups; RBC-C 3bRR and RBC-ICR of the chloral hydrate and sodium pentobarbital intraperitoneal injection group were significantly lower than the other two groups.ConclusionsDifferent drugs can induce changes in immune function of mice at different levels. Isoflurane and ether have less damage to animal body, while chloral hydrate and sodium pentobarbital intraperitoneal injection have a certain inhibitory effect on the animal body respiratory system and can cause greater damage to the body. Therefore, the reasonable selection and control of anesthetics are very important in order to avoid the experimental errors caused by anesthesia.

Effects of atorvastatin on inflammation and oxidative stress

Treatment with inhibitors of 3-hydroxyl-3-methylglutaryl coenzyme A reductase (statins) reduces the incidence of cardiovascular events, but it is unclear whether the beneficial effects are mediated solely by their lipid-lowering properties. We therefore investigated whether atorvastatin reduces inflammation and oxidative stress independently of its lipid-lowering effects. The subjects comprised 71 hyperlipidemic patients (64 ± 9 years old, mean ± SD) who were not receiving medical treatment. Serum lipid and C-reactive protein (CRP) levels, and urine 8-isoprostane level (an index of oxidative stress) were measured before and after 4 weeks of treatment with atorvastatin at 10 mg/day. In 38 patients, these biochemical variables and carotid intima-media thickness (IMT) were also measured after 6 months of treatment with atorvastatin. Atorvastatin markedly reduced CRP (from 0.69 ± 0.36 to 0.42 ± 0.20 and 0.35 ± 0.19 mg/l, median ± median absolute deviation, P < 0.0001), 8-isoprostane (from 225 ± 99 to 178 ± 75 and 179 ± 60 ng/g creatinine, P < 0.05), and low density-lipoprotein cholesterol (LDLC; from 165 ± 21 to 106 ± 18 and 112 ± 17 mg/dl, P < 0.0001) after 4 weeks and 6 months of treatment, respectively. However, the reductions in CRP and 8-isoprostane were not correlated with those of LDLC. After 6 months of treatment, IMT was significantly decreased compared with the baseline value (from 0.94 ± 0.26 to 0.90 ± 0.20 mm, P < 0.05), but this was not correlated with the reduction in LDLC. These results suggest that atorvastatin has beneficial effects on inflammation, oxidative stress, and the lipid profile in patients with hyperlipidemia. The extra-lipid effects are not attributable to the lipid-lowering effect of the statin, suggesting that the pleiotropic effects of atorvastatin are independent of its effects on the lipid profile.     

阿魏酸钠对特发性肺间质纤维化患者氧化应激及肺功能的影响

目的探讨阿魏酸钠对特发性肺间质纤维化（IPF）患者氧化应激及肺功能的影响。方法36例特发性肺间质纤维化住院患者被随机分为A、B两组,A组为阳性对照组,进行常规治疗,B组为治疗组,在常规治疗基础上给予阿魏酸钠,疗程12周。另选取20例健康体检者为正常对照组。测定IPF患者治疗前后及健康体检者肺总量（TLC）、一氧化碳弥散量（DLCO）以及血浆中丙二醛（MDA）、谷胱甘肽过氧化物酶（GSH—Px）的含量。结果与正常对照组相比,IPF患者体内MDA显著升高,GSH—Px含量显著降低,TLC及DLCO也明显降低（P〈0．01）。应用阿魏酸钠后,B组患者上述指标的改善明显优于A组,差异具有显著性（P〈0．05）。结论氧化应激是引起IPF的原因之一,阿魏酸钠可能通过调节氧化应激水平,改善IPF患者的肺功能。
